Title: Improvements in or relating to hydraulic shock absorbers and the like differential pressure operated damping means
IPC: F16F9/44
Filed: 1936-08-08
Abstract: 470,042. Hydraulic shock-absorbers. ARMSTRONG, F. G. G. Aug. 8, 1936, No. 21890. [Class 108 (iii)] In a hydraulic shock-absorber particularly for vehicles, flow of fluid in both directions along a single passage between cylinders 15, is regulatable by three independent controls, one of which is a valve-seating 30, adjustable externally of the shock-absorber, the second of which is a valve adapted to vary the area of the passage in accordance with angular displacement of the operating shaft of the shock-absorber, and the third of which is constituted by a valve-controlled byepass 32, 33, 34 extending between opposite sides of the valve-seating 30. As shown, the second control comprises a valve consisting of a spindle 24, flattened shank 25, and tapered end 27, which is slidable in a boss 23 in the shock-absorber casing and is spring-pressed against a camsurface 13 on the operating-shaft 12 so that its displacement is proportional to the relative displacement of the elements to be checked. The valve seating 30 is formed in a threaded plug 20 so as to be adjustable. The byepass 32, 33, 34 is controlled by a valve 35 having a spindle in screw threaded engagement at its upper end with the casing and angularly displaceable (a) manually by a lever 40, (6) thermostatically by means of a bi-metallic coiled spring replacing the lever 40 and which may have an overriding remote driver's control, or (c) automatically with transverse inclination of the vehicle body by means of a pendulum connected with the lever 40. Alternatively, the valve spindle may be formed in two parts between which a cam is displaceable by a pendulum to vary the position of the valve. The thermostat may be inside or outside the shock-absorber casing. Specification 468,967, is referred to in the Provisional Specification.

Patent GB-630398-A (GB)
Title: A method of and apparatus for making oil gas
IPC: C10G9/00
Filed: 1947-08-14
Abstract: 630,398. Oil gas generation. GAS MACHINERY CO. Aug. 14, 1947, No. 22662. Convention date, March 20, 1942. [Class 55 (ii)] The checkerbrick of an oil gas generator is heated to 1500‹-2000‹ F. by burning oil therein and subjected to a short steam purge to remove all carbon by a water gas reaction ; oil gas is then generated by passing in steam and oil at a velocity insufficient to abstract heat from the brick surface faster than it is conducted from the interior. The brick spacing is sufficiently open to preclude filtering out of carbon. In a generator 1 spaced checkerbricks 3 occupy less than half the volume, the spacing in each layer being not less than 1/3 and not more than the width of a brick, or with material such as silicon carbide with a higher heat conductivity than firebrick, the spacing may be less. A carburetter 30 and superheater 40 have similar checkerbrick layers. For the blast period oil is burnt at a burner 12 with air from a duct 9 until the bricks reach a temperature of about 2,000‹ F., combustion products heating the bricks 31 in the carburetter which are also heated by an oil burner 32, and the combined products passing through the superheater to a flue 44. The carburetter and superheater temperatures reach 1,700-1,800‹ F. and 1,450‹-1,600‹ F. respectively. The burners, air valves and stack valve 43 are then closed and high pressure sweep steam is admitted through a pipe 4 and the new steam through a pipe 14 and shortly afterwards oil is sprayed from pipes 5 and 33. After the run and the oil sprays are shut off, steam pipe 4 remains open for a steam purge followed by an air purge on valves 10, 11 being opened. Stack valve 43 is then opened for another blast period. In a modification, combustion products from down blasts from generator and carburetter working in parallel at 1,500‹-1,800‹ F. pass upwardly through the superheater. In an example an oil gas containing 43.8 per cent methane, 24.2 per cent hydrogen, 16.4 per cent ethylene and 2.6 per cent carbon monoxide was produced with a calorific value of 977 B.Th.U.

Title: Improvements relating to impulsing arrangements for automatic telephone systems
IPC: H04M1/272
Filed: 1930-07-31
Abstract: 359,596. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and CHRISTIAN, D. A., Morven, Charlton Road, both in London. July 31, 1930, No. 23055. [Class 40 (iv).] The transmission of impulses in accordance with the setting of an operator's keyboard equipment is effected by a common impulse cam under the control of a common counting arrangement. In the arrangement shown in Fig. 1, the movement of the digit-distributer switch DD to its fifth position when all the digits have been recorded connects earth back over lead Z causing earth to be returned over lead S to operate relay SS which operates SR. At the commencement of the next cycle of the common apparatus, relay SA operates over the pick-up cam S1 and locks throughout the cycle, connecting impulse relay A to cam S2, and stop relay SZ(i) over contacts of the thousands register MW .. MZ to one of the common counting leads connected to the bank of wiper S3. Impulses are thus transmitted by relay A until the marked counting lead is reached when relay SZ operates disconnecting relay A and energizing magnet CDM to advance output-control switch C one step. The remaining digits are sent out in similar manner after which relay CO(i) operates over wiper C2, locks over lead S and earths lead P. The release of BG restores switches DD, C to normal, relay BP operating in series with the driving magnets to maintain CO operated until restoration is complete. To cancel a wrong setting, earth is connected over leads W, Y, causing relays WK, YK to complete a circuit for relay CK(i) which unlocks any rccording relays and restores switch DD to normal. In a modified impulsing arrangement, Fig. 2, relay P operating over cam S1 at the beginning of a cycle energizes relay SA which locks up over one or more of its windings (i) . . (iv) and contacts of the recording relays. These parallel locking circuits include normally-closed contacts S3w .. S3c which are opened singly and in varying combinations in definite order by rotating cams, impulses being transmitted by relay A until relay SA releases. With this arrangement, codes involving one marking wire only must correspond to smaller digits than the codes involving the same marking wire in combination with one or more others, but in a further modification the codes may be alloted to the digits in any order, the relay SA in this case being provided with four more windings which are associated with break contacts of the recording relays and make contacts of the rotating cams.
